This unnamed island is the seventh island Ash, Iris and Cilan visited during their travels through the Decolore Islands. It is a world famous resort.

After a Croconaw, Azumarill, Octillery and Ducklett stole some supplies on another island, they retreated to this island where they found Meowth, who was then strangled by Octillery. Charizard, who was sent out by Ash to look for the thieves saw this and went back to the first island. The group, along with Porter and Officer Jenny then went to the second island right away. There, they encountered the pirate gang with the gang trying to reason them by telling their harsh past. Meowth translated what they said and told the group that they were Pokémon abandoned by their original Trainers and became distrustful towards humans ever since. After hearing their story, Ash challenged Croconaw and Azumarill to a Double Battle using Pignite and Snivy, and won despite the former having a type-disadvantage.

Team Rocket arrived and wanted to steal the pirate gang but their plans were thwarted by the teamwork of Snivy and Pignite. Suddenly, a storm occurred and a group of Darumaka got into trouble on the rough waves of the sea. The Pirate gang showed their good deeds and rescued them. The Darumaka were then safely returned to their Trainers. Seeing their actions, Officer Jenny decided to have the four Pokémon travel with her and they then waved their farewells to Ash and his friends.
